K Class stars have the following characteristics.
The O spectral class is the highest temperature class. Stars in this class are extremely hot and blue in color, with surface temperatures exceeding 30,000 K.
O, B, and A spectral class stars are less common than G, K, and M spectral class stars. These earlier spectral class stars are larger, hotter, and more massive, leading them to have shorter lifespans and therefore be less abundant in the galaxy.
Spectral class is a classification system for stars based on their temperature and spectral characteristics. It categorizes stars into different groups, such as O, B, A, F, G, K, and M, with O being the hottest and M being the coolest. Spectral class is indicated by a letter, with additional subtype information denoted by a number.
F Class stars have the following characteristics.Temperature: 6,000 -> 7,500 KelvinColour: Yellow-white -> WhiteMass: 1.04 -> 1.4 Solar massesRadius: 1.15 -> 1.4 Solar radiusLuminosity: 1.5 -> 5 Solar luminosities.Rarity: 3% of all main sequence stars.Examples: CanopusSee related link for more information.
O. This is the class of the blue/white giants.
The spectral class letters in astronomy represent the temperature and color of stars. The sequence starts with O (hottest and bluest stars) and ends with M (coolest and reddest stars). The spectral class letters are O, B, A, F, G, K, and M.
The O spectral class is the highest temperature class. Stars in this class are extremely hot and blue in color, with surface temperatures exceeding 30,000 K.
Class II: yellow stars-hydrogen less strong, but evident metallic lines, such as the Sun, Arcturus and Capella. This includes the modern classes G and K as well as late class F.
O, B, and A spectral class stars are less common than G, K, and M spectral class stars. These earlier spectral class stars are larger, hotter, and more massive, leading them to have shorter lifespans and therefore be less abundant in the galaxy.
